Abstract

Cloud storage with searchable encryption enables document retrieval from remote databases but requires sharing search keywords with database owners, raising privacy concerns. To address this challenge, this project integrates Blowfish encryption with Block chain technology to ensure secure, reliable, and efficient medical data storage and access. Blowfish, a robust symmetric-key block cipher, encrypts sensitive medical data, ensuring privacy even in case of unauthorized access. Blockchain provides a decentralized, immutable ledger to log transactions and access requests, enhancing data integrity. The proposed approach employs cryptographic methods and index structures to enable secure and efficient keyword searches on encrypted data. A secure index is generated during encryption, facilitating quick retrieval without exposing plaintext data. Access control mechanisms ensure that only authorized users, who possess the correct decryption keys and have their identities verified, can access the data. Additionally, the key verification process notifies data owners of unauthorized attempts. This solution achieves a balance between data privacy and search functionality by enabling keyword-based retrieval of encrypted cloud-stored data while ensuring the protection of sensitive information. The method demonstrates a practical and secure technique for cloud-based medical data management, maintaining confidentiality and integrity against potential threats.
